Combustion pressure

The complex combustion processes inside combustion engines are required to measure the gas and fluid pressures at many different positions and physical conditions. AVL offers several different pressure sensors for every specific task.

The following table is a short overview of the complete pressure sensor portfolio from AVL. Detailed technical information can be found in the "Download" tab-section and in the sensor catalog.

Please note, AVL introduced the PH08 flame arrestors as the successor of PH03 flame arrestors. AVL stopped selling PH03 and its compatible sensors. Documentation which promotes PH03 and its related products can be seen as outdated and will be corrected soon.

CYLINDER PRESSURE

These sensors
measure the pressure
inside the combustion
chamber. Installation
can be done either via
spark-plug and glow-
plug adaptors or via an
separate indicating
bore inside the cylinder
head.
Beside the wide variety
of different sensors of
the portfolio we offer on
demand custom
tailored solutions for
spark-plugs and glow-
plugs as well.

ENGINE MONITORING

These sensors can be used in long-term and permanent installation for non-stop engine monitoring. Their strength is the fusion of robustness and measurement stability.
